Girls, hello, I have a question for experienced moms, my baby is one month old and her stool has changed, we're on IV, formula was still changing because there were colic and constipation, hard stool was, switched to Maluka and everything is good, but the stool changed, and I started worrying. Is it normal or should I be worried? Sorry for the photo
